match: don't print explicitly listed files with wrong case (BC)

On case-insensitive file systems, if file A exists and you try to
remove it (or add, etc.) by specifying a different case, you will see
something like this:

  $ hg rm a
  removing file A

I honestly found this surprising because it seems to me like it was
explicitly listed by the user. Still, there is a comment in the code
describing it, so it is very clearly intentional. The code was added
in baa11dde8c0e (match: add a subclass for dirstate normalizing of the
matched patterns, 2015-04-12).

I'm going to do a lot of refactoring to matchers and the feature
mentioned above is going to get in my way. I'm therefore removing it
for the time being and we can hopefully add it back when I'm done.
